T3-10 High Linearity Triple Balanced Microwave Mixer

The T3 mixer is the most advanced mixer circuit available in the world. In addition to broadband overlapping LO, RF, and IF bands, it has the potential for extremely high linearity. Since it is a true-commutating mixer, it will provide increasing two-tone intermodulation suppression, input 1-dB compression, and spurious suppression (for most spurs) as the rise time of the LO signal is increased by either increasing sine wave LO drive or using a square wave LO. To generate a fast rise time LO signal Marki recommends the use of an integrated or stand-alone saturated LO amplifier. Much more detailed information about the T3 can be found in our T3 Tutorial.
